Product information - Prime X299-A, Intel X299 Mainboard - Sockel 2066

The ASUS PRIME X299-A from ASUS represents a platform-leading motherboard for High-End Intel processors from the Skylake-X and Kaby Lake-X generations that work with the X299 chipset and require an LGA 2066 socket. This chipset, codenamed "Lewisburg", makes a robust contender thanks to its up to 30 HSIO lanes (High-Speed Intput/Output) as well as the maximum of 24 PCIe-Express 3.0 lanes. This motherboard is a powerful all-rounder that allows more devices to be connected internally and used simultaneously.

The ASUS PRIME X299-A Motherboard at a Glance:

  • 3× PCIe (3.0/2.0) x16 (2× x16 / 1× x8)
  • 3× USB 3.1 (1× Type-C / 1× Type-A / 1× internal)
  • 8× USB 3.0 (4× Type-A / 4× internal) & 4× USB 2.0 (4× Type-A / 2× internal)
  • 1× M.2 (SATA6G & PCIe 3.0 x4) / 1× M.2 (PCIe 3.0 x4) / 8× SATA 6G
  • 8× DIMM-Slots for DDR4-RAM (max. 128 GB with 28 or 44 Lane CPU)
  • Asus LED Strip Header and Aura Sync RGB-LED lighting

The ASUS PRIME X299-A in Detail

The ASUS PRIME X299-A is a well-equipped enthusiast-level motherboard in the ATX format and is designed for power users and case modders wanting an X299 & Skylake-X or Kaby Lake-X compatible motherboard. The stylish black board comes with three PCIe x16 slots, of which two are connected to the chipset via 16 full lanes and are connected electrically with eight data lines. This allows the use of even NVIDIA 3-Way-SLI or AMD 3-Way-CrossFireX configurations when using a 28 or 44 lane CPU.

Equipped with a total of eight DDR4-DIMM, a CPU with 28 or 44 data lines can operate all slots in Quad-Channel mode with up to a maximum capacity of 128 GB of memory. A CPU with 16 lanes supports Dual-Channel mode over four slots with a maximum capacity of 64 GB. Officially DDR4 modules can be used at up to 2.666 MHz, and clockspeeds of up to 4.000 MHz after overclocking!

The board comes with an extensive array of data storage devices including two M.2 slots for ultra-fast NVMe-M.2-SSDs and eight SATA-6G ports for 3,5" or 2,5" hard drives and SSDs (incl. RAID support). The M.2 ports are connected to the chipset over four PCIe 3.0 lanes and, in combination with the NVMe protocol, this enables a transfer rate of almost 4 GB/s. This makes M.2-PCIe SSDs up to eight times faster than SATA-6G SSDs!

Externe Anschlüsse

The I/O bracket of this performance-oriented motherboard comes with various useful ports to make life easier for users. Besides a new USB 3.1 Type-C port, which is particularly thin and can be inserted in either orientation, the board comes with an additional backwards compatible USB 3.1 port. Thanks to the ASMedia 3142 USB 3.1 controller speeds of up to 16 Gbit/s can be reached, which is three times as fast as previous USB 3.0 ports. Naturally the board comes with four additional USB 3.0 and two USB 2.0 ports.

For unhindered network connectivity the ASUS PRIME X299-A also comes with an Intel Gigabit LAN port. Quality sound is provided by the Realtek ALC1220 Codec and this is supplemented by a total of five gold-plated audio ports and an optical Toslink digital out.

Additional Features

Counting among the unique features offered by the ASUS PRIME X299-A is the RGB-LED lighting thanks to ASUS' Aura Sync. Apart from two lighting zones directly on the board, several LED strips can also be connected and perfectly controlled via the Aura Sync software. A USB 2.0 port can also be used as a BIOS-flashback option.
